CAM.

Specification of Letters Patent.

'latented Mar. 13, 1917.

Application filed May 25, 1916. Serial No. 9 9,779.

To all whom it may concern:

lie it known that l. MARION It. (.AsnY, a citizen of the United States of \merica,.and

a resident of (Tlinton, county of Laurens, State of South tarolina, have invented certain new and useful Improvements in Cains, of which the following is a full and clear specification.

This invention has relation to the type of cam patch covered by my latent 1',177,30-l, dated March 28, 1916, in which a worn or tiou of the periphery of the cam is bri ged by a patch plate bolted to the side of the Cam body and having its periphery in alinement with the periphery of the cam, this patch being secured to the cam body by means of a pair of bolts, one at each end of the patch plate.

The object of the present invention is to so construct the patch plate that it may be secured in place by but a single bolt, usually the bolt that secures the cam point or toe to the cam body, as more fully hereinafter net forth.

In the drawings Figure 1 is a viewof one of the styles or types o cam to which my device is applicable;

Fig. 2 provided with my patch device;

Fig. 3 is a radial section through the line :-5 of Fig. 2';

Fig. 4 is a section through the line 4-4 of Fig. 2; and

Fig. 5 is a perspective viewpatch detached.

Referring to the drawing by of the cam reference characters, a' designates the usual toe or v mint member which is bolted to the cam body in the usual mannerby a bolt 1/. The rim of the cam is connected to the hub by means of spa ed spokes c. The patch plate 1/ is removably fastened to one face of the cam body by means of the. aforesaid bolt 1) at one end. and, t the other end, by means of a lip or lug c engaging behind one of the adjacent spokes.

This patch is adapted to bridge the worn" parts f (shown in Ijig. 1) of the periphery of the cam just back of the toe c, and the parts are proportioned that when the patch-plate is locked in position against the is a side elevation of the same cam,

cam,.the perip icral edge or face of the patch plate will brid 1c the worn part and virtually form a continuation of the peripheral surface proper of the cam body. Preferably, the inner face of the cam plate is shaped to fit within the sector-slmped opening between the spokes, so as to thereby assist in rigidly holding the patch in position. so

I have illusnrated my device as applied to a type of can? which wears most at a point back of the toe member. It will be understood that the patch plate is to be shaped to suit the necessities of the cam to which it is to be applied, and it will therefore be understood that I do not restrict myself to any particular fo'm of patch plate or to any particular st le of cam, so long as the cam body is pro\ ided with a hole or recess through whic 1 the locking lip or lug may be passed to enaole it to engage the side of the cam opposite to that against which tliecain patch bears,

l-laving thi s described my 1 claim is:

1. In comllination with a calnhaving an opening in is 'body portion, a patch plate and a bolt for attaching one end of said plate to the cam b idy, said cam plate being provided with a lip or lug extending through said opening and engaging the opposite face of the cam b idy. whereby the patch plate is removably l ickcd in position against the cam body by a single bolt.

1 The col ibination with a cam having a removable toe member and a bolt for fastening the toe nclubcr to the cam body. of a patch plate uaving one end secured to our side of the ram body by the aforesaid bolt and having ts other end extending through an opening in the cam body and engaging behind the opposite face of the cam body. said patch p atc having a peripheral surface in alinemcnl with the peripheral surface of the cam.

3. ln comdination with a cam body having. an opening therein at a distance from its periphery, a patch plate having on one face an enhirgcmcnt shaped to lit in said opening and having its periphery inalincnu-nt with the periphey of the cam body, and means for fastening the patch |ilat removably to the cam bot' y.

an opening therein,

4. In combination with a cam bod ce shaped to fit in said openin a patch plate having one and havy having of the cam body posite face of th and a lip engaging the ope cam body.

I n testimony whereof I hereunto aflix my ing its periphery in alinement with the esignature.

riphery of the cam body, and means or 3 MARION R. CASEY. fastenin the .patch plate removably to the Witnesses:
